SPEGIFICA.TIOIT forming: part of Letters Patent No. 752,053, datedFebruary 16, 19O4=.- Application filed June 4, 1902. Serial No. 110,131.(No model.) I

Toall whom it may concern:

Be it known that I, ALFRED C. EINSTEIN, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Acetylene-GasGenerators, of which the follow-ing'is a full, clear, and exactd'esci'iption, reference being had to the accompanying drawings,frmingpart of this speci- My. invention relates to that class of gasgeneratingapparatus utilized in the production of acetylene gas from calciumcarbid,-the invention having for its object the production of agenerator in which a normal pressure and amount of gas will bemaintained, due to the construction and arrangement of the waterdeliveryparts of the apparatus and the con-- vnection of the gas-conveying pipesin such manner that the .gas evolved in the apparatus constantly acts toregulate the amount of Water fed to the carbid;

- subdivided by partitions 3 and 4. The parti tions 3 and i are unitedby a central tube 5, and the partitions divide the interior of the tank'into three chambersviz. a generatingchamber 6, in which the carbid iscontained, a water-chamher7, from which the water is conveyed to bedelivered into the generatingchamber, and a gas-chamber 8, into whichthe gas passes as it is produced in the generatingchamber. l 4

9 designates a water and gas conducting tube seated. in the tube 5 andextending from the generating-chamber to the gas-chamber, the tube beingopen at both ends to communicate with said chambers.

10 designates a water-feed pipe provided with legs 11 and 12, that areopen at their ends service.

that water in said chamber may enter the legs to pass upwardly throughthe feed-pipe. The

feed-pipe is preferably inclined upwardly from one of the legs, and itis positioned the conducting-tube 9 and provided with a restrictedoutlet-nozzle 13, through which the water finds egress from thefeed-pipe into the conducting-tube to descend therethrough onto thecarhid in the receptacle 2. 4

14 designates a supply-tank provided with 'an inlet 15, closed hy a cap16.

17 is a supply-pipe provided with a valve '18 and leading to the tank 1,to which it is connected at the bottom of the water-chamber 7 19 is adrain-cock fitted to a supply-pipe 17.

- 20 is a relief-pipe connected to the supplypipe 17 below the valve 18,that is positionedin said pipe and extends upwardly into the supply-tankl tto' the upper end of said tank. 21 is a blow-off at the top of thesupply-tank. 22 is a gas-delivery pipe leading from the upper end of thegenerator-tank l and having to communicate with t-ldilttithf-ohamber '7,so

and introduced into said tank at the upper end of the waterrchamber 7.

' In the conducting-tube 9 I provide one or more orifices 9, throughwhich the condensed water resulting from vapor that rises into thegas-chamber 8 from the generating-chamher may be returned to thegenerating-chain her on falling to the dished partition i, whichconstitutes the bottom of the gas-chamber.

'In the practical use of this generator carbid is placed in thereceptacle 2 previous to its being afiixed to the generator-tank, and onthe application of the carbid-receptacle to the tank the apparatus is incondition for Water is introduced into the sup ply-tank 14: through theinlet 15 and passes therefrom through'the supply-pipe 17 to theWater-chamber 7 in the tank 1, the amount of water introduced beinggoverned by the 10.-

cation of the inlet, which ispositioned sothat the supply-tank will beonly partially filled when-the water-chamber is full. When thedesiredamount of water has been introduced, the valve 18 may be closedto shut off the passage of water from the supply-tank to thewater-chamber until such time as may be desired to eflect generation ofgas. On the opening of the valve 18 the water contained by thesupply-tank descends through the supply-pipe 17 and enters thewater-chamber 7, with a result that it rises through one of the legs 11or 12 of the feed-pipe to escape through the restricted outlet-nozzle 13and descendsthrough the conducting-tube 9 into the generating-chamberonto the carbid in said chamber; While I have shown the feed-pipe 10 asprovided with two legs, I do not limit myself to the use of both ofthese legs, as one of them would be ample under fnany conditions. By thedelivery of water to, the carbid in the manner explained generation ofgas is produced and the gas passes from the generating-chamber throughthe tube 9 into the gas-chamber 8and generation being continued withoutcessation so long as excessive pressure is not produced. In the resultof excessive pressure of gas the gas after passing into theconveying-pipe 22 returns to the generator-tank through the returnpressure-pipe 24 and enters the water-chamber 7 'to exert pressureagainst the water in'said chamber. In such case the water in saidchamber is driven downwardly therein by the pressure of gas and ascendsthrough the supplypipe to be returned to the supply-tank 14, therebyloweringit away from the leg or legs of the feed-pipe 10 and causingcessation of I delivery of water through said feed-pipe.

The pressure of gas holds the water in the chamber 7 away from thefeed-pipe until the gas-pressure again becomes'normal in the gas-chamber8, when upon reduction of pressure the water returns to thewater-chamber and delivery through the feed-pipe is again established asbefore to renew the generation of gas.

In the'event of excessive pressure of gas occurring after the apparatushas been shut ofi' by the closing of the valve 18, that controls thesupply-pipe 17, the excessive pres sure may find egress from thewater-chamber 7 by passing through the water therein and through thesupply-pipe 17 to the relief-pipe 20, through which it is delivered intothe supply-tank 14 to escape through the blow-off or safety valve 21.

I claim as my invention i 1. In an acetylene-gas generator, thecombinatio n of a generating-chamber, a waterchamber, a gas-chamber, atube prov idingcommunication between said generating-chamber and saidgas -chamber, a feed-pipe having a leg arranged in said water-chamberand seated in said pipe, an outlet-nozzle on said feed-pipe in saidtube, a supply-tank, a supply-pipe leading from said supply-tank to saidwater-chamber, a gas-conveying pipe leading from said gas-chamber, and areturn-pipeleading from said gas-conveying pipe to said water-chamber,substantially'as and for the purpose set forth.

2. In-an acetylene-gas generator, the combination of--agenerating-chamber, a'waterchamber, a gas-chamber, means for deliveringwater from said water-chamber to said generating-chamber, awater-conveying pipe leading from said gas-chainber,a return-pipeleading from said gas-pipe to said water-chamber,

asupply-tank,asupply-pipeleading from said 8o.

supply-tank to said water-chamber, and a relief-pipe leading from saidsupply-pipe into said supply-tank, substantially as described.

3. In an acetylene-gas generator, the combination of agenerating-chamber, a waterchamber, a gas-chamber, a tube providingcommunication between said generating and gas chambers,- and provided atthe bottom of said gas-chamber with an orifice, a water-feed pipeleading from said water-chamber to said tube and having anoutlet'arranged in said tube, substantially as described.
